Cabins for suction pressure sandblasting have been designed to sandblast modest quantities of medium/small parts. They are very practical machines, with the operator placed outside them, with blow-by and “pneumatic washing” of the abrasive for sandblasting and without powder release in the outer environment.
In such plants a depression is created , through a Venturi system, piping the abrasive from the collection hopper and launching it towards the pieces to be sandblasted; therefore it is possible to employ only non-metallic abrasives (corundum, glass micro-spheres, garnet, ceramic micro-spheres, plastic granules, etc.).
Compared to a pressure sandblasting cabin the launch speeds will be lower and surfaces will be obtained with a “soft” finishing.
It is possible to assemble a filter box in case of frequent sandblasting. In case of sporadic use, a filter bag can be assembled as an alternative.
Shot-peening machines can also be equipped with:
- extractable rotary table: for encumbering and/or bulky parts;
- rotary basket: for small metallic items.
Small cabins are made on demand.
They are used to sandblast all metals in general, glass, natural stone (marble, basalt, etc.), wood, ceramic, etc.
